APPARATUS FOR IMPREGNATING MATCHES .OIE WOOD, PASTEBGARD, PAPER; OR THE Linn WITH PARAFFIN;

Application filed March 25, 1922. I SerialNo; 5463M.

To all whom it may concern:

Be it known that I, KARL soHALn, engineer,

of Saxony, German Republic,

PAUL Gerrand resident of 19 Reickerstrasse, Dresden, Republic of Saxony, German Republic, have invented a new and useful Apparatus forlmpregnat ing Matches of Wood, Pasteboard, Paper. or the like with Paraffin, of which the followinn isa specification. 1 I I The present invention has for its object an apparatus for impregnating; ,matches; of

wood, pasteboard, paper or thelike withv paraffin. The novelty of said apparatus consists in that two discs vertically rotating; within a receptacle filled witlrparaffin and heated in a convenientmanner are coated on their inner surfaces with felt or another material absorbing the paraffin in such a 0 manner that during the rotary movement of the discs and their passage through the liquid parafiin the latter is absorbed by the felt which supplies the parafiin for the purpose of impregnation to the wood, paste- 2 board or paper band or stripe passing at the top between the two discs and forming the matches. The discs coated with felt on their inner facing sides are arranged at a defined distance from each other and can be adjusted one to another.

A supply-container is arranged at the side of the receptacle and used for heating and supplying the latter with fresh liquid paraffin. The receptacle and the container are separated one from another by a partition provided in its lower part with openings by which the receptacle is connected with the container in such a manner that a preliminary heating of the paraffin within the container on the onc'hand and a supply of fluid paraffin to the receptacle on the other hand is ensured by the supply of liquid paraffin into the container heated in any convenient manner. The container is provided with a bottom slanting towards the receptacle for ensuring a complete emptying of the container and a continuous supply of liquid paraffin to the receptacle from said container.

For the purpose of ensuring an. easier transfer of the paraffin from the felt or any other absorbing material onto the matches a subject of the Republic suitable absorbing m aterial.

formed of wood, pasteboard, paper/or the like with an impregnating-apparatus ar 7 In the accompanying drawing Fig. l] is a plan and Fig. 2 a longitudinal section of a structure showing my improvement embodied in one form in an impregnating-apparatus. Fig. 3 is a vertical sectionof the impregnating device of the apparatus menti'oned.

In the said drawing, a is the receptacle,

b Z) are two discs rotatably arranged on a horizontal shaft in a defined distance and adjustable one towards another and c is'a layer coating the inner side or surface of said discs and consisting'of felt or other tainer being in connection with the receptacle a by openings 0 provided in the lower part of a partition 7 in such a mannerthat the receptacle an is constantly filled with liquid paraflin on supplying the container. (Z with fresh or liquid paraffin. g is a bottom closing; the lower part of the container d and slanting towards the receptacle (1 so as to ensure a continuous supply to the receptacle. The receptacle a and the container (Z are heated in a suitable manner whereby the parafiin of the container is preliminarily warmed and kept in a fused state in said container and in the receptacle.

71. is a device arranged in front of the impregnating apparatus proper and used for preliminarily heating or warming the match-band to be impregnated. Said device can be formed by two heated boxes 2' i dis a con between which the match-band Z can be passed. In case of necessity, two guideplates m? m situated at the inner wall of the heated boxes may be arranged, said plates being heated by the boxes i 71 and transmitting their heat to the match-band running along the guide-plates, so that thls felt-coated discs match-band is in contact with the heatingdevice for a longer period and a better preliminary heating of said band is ensured.

What I claim is:

1. In an apparatus for impregnating matches of wood, pasteboard, paper or the like with paraffin, in combination with a receptacle filled with paraffin, of discs rotatingwithin said receptacle, arranged in a defined distance from each other and adjustable one towards another and layers of absorbing material coating the inner facing surfaces of said discs and transmitting the paraffin to the matclnband passed between the upper parts of the discs mentioned.

2. In an apparatus for impregnating matches of wood, pasteboard, paper or the like with paraffin, in combination with a receptacle filled with parafiin to be heated, of

rotating within said receptacle, a heated parailin-container for preliminarily heating the paraliin, a partition situated between the receptacle and container mentioned, openings provided in said partition to ensure the continuous supply of the fused parafiin from said heated container into the receptacle.

3. In an apparatus for iin 'n-egnating matches of wood, pasteboard, paper or the like with parallin, in combination with a heated receptacle filled with paraliin offeltcoated discs rotating within said receptacle, a heated parai'lin-container, a device for preliminarily heating the match-band situated in front of the impregnating apparatus proper, a partition provided with openings and sit uated between the receptacle and the 001k tainer, so as to ensure a continuous supply of fused paraliin from the container into the receptacle mentioned.

4. In an apparatus for impregnating matches of wood, pasteboard, paper or the like with paraiiin, in combination with a heated-paraiiin-receptacle of feltcoated discs rotating within said receptacle, a heated paraffin container, for preliminarily heating the paraiiin a device for pnelin'iinarily heating the match-band situated in front of the impregnating-apparatus proper and consisting of heated boxes for passing the match-band between the inner walls of the boxes is passed a partition provided with openings and situated between the receptacle and the container, so as to ensure a continuously supply of liquid or fused par afiin from the container into the receptacle mentioned.

5. In an apparatus for impregnating matches of wood, pasteboard, paper or the like with paraiiin, in combination with a heated parafiin-receptacle, of felt coated discs rotating within said receptacle, heated paraflincontainer for preliminarily heatiug the parallin a device for preliminarily heating the match-band situated in front of the 'impregnating-apparatus proper and consisting of heated boxes for passing the match-band between the inner walls of the boxes is passed, guide plates fastened to saidboxcs and directly heated by them for conducting the match-band between the plates mentioned, a partition provided with openings and situated between the receptacle and the container so as to ensure continuous supply of fused paraflin from the container-into the receptacle mentioned;

In testimony, that I claim the foregoing as my invention I have signed my name this 15th day of February, 1922.
